Review on ONeal Unisex Adult Full Face Sierra Helmet Motorcycle & Powersports by Roy Bush

If a snowmobiler is purchasing this helmet be aware that the visor will fog up profusely! Realized that it's not really designed for use in the cold and I wish I had known that before buying. However, after some research, I was able to discover that a few additional accessories can help combat fogging, most notably a double lens visor with a heating element. I found the Castle X Mode Dual Sport SV to be basically the same helmet just different branding like the difference between Chevy and GMC, same truck with a different emblem. Now you can just return the ONEAL helmet and get Castle X or do something else. I have made and received replacement parts for the Castle X helmet such as: visor, respirator, chin curtain and this will help prevent fogging of this ONEAL helmet. I hope it helps and if you don't believe me take a picture of both helmets and compare them you'll see what I mean
